Magnesia Carbon Brick
Description
This kind of basic refractory brick's ( magnesia carbon brick ) raw material is mgo, the quality of magnesia has an extremely important influence on the performance of magnesia carbon bricks. The purity of magnesia has a significant impact on the slag resistance of magnesia carbon bricks. The higher the magnesium oxide content, the lower the relative impurities, the lower the degree of silicate phase separation, the higher the degree of direct bonding of periclase, and the higher resistance to slag penetration and slag melting loss. The impurities in magnesia mainly include calcium oxide, silicon dioxide, and iron oxide. If the content of impurities is high, especially boron oxide compounds, it will adversely affect the refractoriness and high temperature performance of magnesia.
Features
Magnesia carbon bricks have many excellent characters such as good high temperature resistance, strong slag resistance, good thermal shock resistance , low high temperature creep and so on.
Application
Magnesia carbon bricks are mainly used for lining of converters, AC electric arc furnaces, DC electric arc furnaces, and slag lines of ladle.

Productive Process
1.Raw material quality control including physical and chemical testing.
2.Crushing and grinding of bulk raw materials.
3. According to customer data sheet required to mixing Raw Material.
Pressing or shaping the green brick depend on different raw material and brick shape.
4.Dry the bricks at dryer kiln.
5.Put the bricks into the tunnel kiln to burning by higher temp from 1300-1800 deg.
6.The quality control department will inspect the finished refractory bricks random.
Packing And Shipping
Packaging according to safety sea-exporting packing Standard
Dispatch : loading the finished packing material at factory by container Door toDoor
By sea fumigated wooden pallet + plastic belt + plastic film wrap.
